A10 Networks (ATEN) CEO Dhrupad Trivedi Withholds Shares for Taxes

What Happened
Dhrupad Trivedi, CEO of A10 Networks (ATEN), had a total of 72,047 shares withheld to satisfy tax withholding obligations related to vested restricted stock units. The withholding transactions were reported as disposals: 10,102 shares on 2026-01-31 at $17.44 each ($176,179) and 61,945 shares on 2026-02-01 at $17.44 each ($1,080,321), for a combined value of $1,256,500. This was a tax-withholding disposition of vested RSUs, a routine administrative transaction rather than an open-market sale motivated by investment views.

Context
Tax-withholding dispositions (transaction code F) are common when restricted stock units vest and the company withholds shares to cover payroll taxes. These transactions are administrative and generally do not signal the insider's view on the company’s stock. The filing shows vesting of both performance-based and time-based RSUs; no open-market sale or option exercise was reported here.
